Get ready to laugh your wrasse off (as in cleaner wrasse – you know, the cute little symbiotic fish that nibbles parasites off its neighbors)! This week, NightLife partners with SF Sketchfest for a night of “weird science” comedy with an 80s twist, featuring festival favorites Adam Savage of MythBusters, Chris Hardwick of Web Soup and the Nerdist podcast, Kasper Hauser, Brian Malow, Joe Klocek, Alex Koll, Emily Heller, Edwin Li, Dave Thomason and Casey Ley; newcomers Veronica Belmont, Dhaya Lakshminarayanan, Nina G.; and more. Think stand-up, sketch, storytelling, conversation and trivia, all blended into one stellar night. DJs Skip and Shindog from New Wave City, organizers of the city’s top 80s dance party, will be spinning in the east pavilion, while Eli Glad and Sleazemore bring their electro sounds to the coral reef. The planetarium will feature a tour of the universe during Science Tonight: LIVE @ 6:30, followed by two showings of Life: A Cosmic Story.

This week, NightLife works up a sweat in preparation for The San Francisco Marathon. CHEER SF will pump up the crowd with two performances in the East garden, followed by a costume contest for the best in workout attire (see below for categories). The SF Marathon crew and race partners will host interactive components including a chair massage station by Everest College, a yoga station from Lululemon, strategies from Bootcamp SF, UCSF RunSafe gait analysis and injury prevention advice, and contestants Ada Wong and Jesse Atkins from The Biggest Loser Season 10 leading a circuit workout. Plus, a series of creative short clips made just for planetarium domes at 6:30. Music by DJ Kap10.
